lo (l/i' ylello/ll, if may concern:

lle il. known that l, 'llnnnr lll. Born, a, eiliaen or" the United States, residing at Vree-ion. in the county/.of tUnion and State if iowa. lla-re invented eertainnew and neenl lnlprovenlenrs in ,Llrxlelrivegof which :he following is a. specification.

lille invention relates to axle drives iorllll'o-l'ehicles. and one eff the principal obleere of the invention 1ste :provide reliable and ellieient means for drivingv the iront or rear axle. or hotll, without interfering with ilu slewing lneehaniern.

flnolher object of the invention is to provide a iront and rear axle drive7 which will uol interfere with the steering nlerhanieln i ille Viront axle and which will prevent slndd'ing. which will add extended life to lires and which will he easier to run over rough roads, and pull out of cavities in the.

reads.

These and other objects may he attained hy means of the construction illustrated in (he :levainpanning drawings. in which:

Fien 'e .i is central, 'vertical section llllo. Y.ile iront Wheel. Fig. Q is a central, ver i; filon of ille wheel, laken at r1ght angie# to Flex l is a vertical sec lion taken on line 3-3 olf Fig. l, looking in ille direelion indicated by the arrows. l'in'. l ie a View in elevation of the steeringr lingg.

ileferringr 'lo the drawings the numeral l ilefsignalee the axles, 2 are tlle` Wheels and l are ille' spokes. 'lhe opposile ends of the axle l are Squared aS at l and ltcd inlo a squared socket 5 formed on a universal Iioint llleinller (i. The socket 5 is round upon ils older side and provided with a, roller hearingl or sleeve 'i which rotates within lhe yoke bl connected lo the axle sleeve 9. .Formed on the yoke S is one member 100i a flohe joint. The yoke S is provided with perforated ends for the Studs 1l formed upon the sieeringr knuekle band Vl2. which is iorllled in lwo nee-lions secured together hy holle lil extending lhrougll flanges lol-ined on ille sections as shown in Figs. 2

and i. 'ille hand l2 is Seated in a groove surrounding ille hall bearing ringY 14, said ring haring' an inwardly projecting central porlion' i5. Ball scones lo and I7 are placed against ille projeetini; portion l5, and the halle in are held in position, by means of the' (lai-ing end 1.9 of the universal joint member a on one side, while the'end of the huh casting E hears 'against the balle upon the other side. The lnen'llher l0 andthe hul) casting' 20 are lrelatively adjuelahle to lake up loef. motion at the vleali hearing, hy means ot' a'tllreadml connection 2l.

- The universal joint nlenlleer 6 is Suhstan 'tially rectangular and is connected nt its ends hy means of a pin 22 extending through a reetanggfularblock 23, made in two eefstioils connected together by pins 24. The block 225 is reeessed to receive headed Stride` iournaled ill the hiiurraied porlioul; 2(3 the universal joinl nleulller 2T. il pin 2H projects through llleeenlerof the pin Q2 lo prevent thewithdrawal of the pin The front end of the member 2T is squared.

as at 29, and the projecting portion of the outer globe' joint member lil" is provided with a squared socket for the squared portion Q9. At the interior screw threads are for the engaging of a nui; 3l fitted to the smooth portion 32 of a pinhaving; a thread` ed portion 33 tilted into a threaded soel'ft in ille end of the squared .portion 29.

inns pin is provided with a slot for a screw' driver for turning it into the socket. and a lock n'ut 34: is fitted to the reduced end for holding the parts yin proper position. A. pin 35 extends 4through the threaded portion ot' the member lO1 and into the nut 3l. .ik threaded cap nnt 36 is lililed io the end of the llubrasting 20 and the ends are slitted 5o thalthe cap nut will firmly hold the parts in place. leather cover or ilap 37 is se cured to the 'oall bearing` ringl and preveurs dust and dirt from getting inlo the hearings.

From the foregoing' it will he understood that the axles may he driven by any suitable gearing' and that lheeleeringl rear will not inlerfele w ith the axle drive. The universal joint is entirely inelosed within the flolle members, and can not he clogged by dust or dirt, while the hall hearings are in closed and can be adjusted to take up lest motion and the parte firmly held in adjusted positions. y

The advantages of a iront and rear axle drive may be briefly referred to as follows:

lSkidding is prevented owing to Faet that the brakes may he applied to hun axles.

rl`here is also a material saving in -.lle weer o1 the tires.' and the element"I of sarety can not be lost sight of.

It will be understood that the mechanism vfor driving the front and rear axles, or the front axle alone, forms no\ part of my pres ent invention.
